1. Rationale

The following terms are being balloted for addition to the terminology document. Items 1 to 7 are being re-balloted in recognition of persuasive negative votes on an earlier ballot. Items 8 to 12 are being balloted for inclusion for the first time. Item 1 somesthesis, , n sensations including touch, temperature, pain and irritation derived from stimulation of the skin and internal organs. (2014) Item 2 chemesthesis, n - sensations derived from chemical stimulation of the skin and internal sensory organs. (2014) Item 3 kinesthesis, n - sensation of bodily movement and position derived from skin and internal sensory organs. (2014) Item 4 temporal dominance of sensations method, n a procedure for identifying the dominant attributes from among a list of sensory attributes as they are perceived over time. (2014) Discussion Dominance is explained as the attribute that catches a panelists attention, which is not necessarily the most intense attribute. In some applications of this method, the intensity of each dominant attribute also is rated. Item 5 labeled magnitude scale (LMS), n a semantic scale of perceptual intensity characterized by approximately logarithmic spacing of verbal labels along a line scale. See figure 2. (2014) Figure 2. Labeled Magnitude Scale. Item 6 labeled affective magnitude scale (LAM), n a type of labelled magnitude scale, with verbal labels related to liking and disliking. There is a neutral point in the center of the line scale and the opposing end anchors are greatest imaginable like and greatest imaginable dislike. See figure 1. (2014) Discussion - The remaining verbal anchors are equivalent to the anchors used with the well-known, nine-point hedonic scale, from like extremely to dislike extremely. Positions of the verbal anchors were determined by magnitude estimation. Figure 1. Labeled Affective Magnitude scale. Item 7 projective mapping, n A sensory method in which assessors arrange test samples on a surface such that samples that are perceived to have similar sensory properties are placed closer to each other and samples that are perceived to have different sensory properties are placed further apart from each other. (2014) Discussion Projective mapping is also known as napping. When assessors add descriptors of the test samples to the projective map, which are used to interpret the sensory differences among the samples, the technique is referred to as Ultra-Flash Profiling. Item 8 napping, n see projective mapping. (2014) Item 9 end effect, n effect where the end points of a scale are used less frequently than other scale points. Item 10 unipolar scale, n scale where the end anchor represents a single direction or continuum of a sensation. Item 11 alpha risk, n the probability of concluding that a perceptible difference exists when, in reality, one does not. (2014) Discussion: alpha risk is also known as Type I Error or significance level. Item 12 beta risk, n the probability of concluding that no perceptible difference exists when, in reality, one does. (2014) Discussion: Beta risk is also known as Type II Error.
